missing no....1,3,7.15_____,_______
The difference of 1 and 3 is 2.
The difference of 3 and 7 is 4, or 2+2.
The difference of 7 and 15 is 8, or 4+4.
Thus, the next number would be 8+8 larger than 15,or 15+16=31.
The next number would be 16+16 larger than 31, or 31+32=63.
The numbers are then 1,3,7,15,31,63.
